摘要
为了适应工程材料的残余应力无损测量的要求,本文将横波和纵波声弹性相结合,建立适用於弱正交异性材料的平面声弹性残余应力测量方法,并应用该方法及自行研制的横波换能器对焊接试件的二维残余应力进行了测试。
An acoustoelastic method for residual stress measurement in slighlty orthotropic material by using ultrasonic longitudinal and shear waves is presented, a shear transducer with small vibrator 2×2mm^2 is described, and the measurements of 2-D residual stresses in a seam welded plate were carried out using this method and shear transducer.
